CASH REGISTER AND INDICATOR.

SPECIFICATION forming part of Letters Patent No. 484,296, dated October 11, 1892.

Application filed April 22, 1892. Serial No. 430.203. (No model.)

To all whom it may concern.-

Be it known thatl, THoMAs OARNEY, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash Registers and Indicators, of which the following is a description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates more particularly to the indicating mechanism of such machines, and in the drawings I have shown only such mechanism and enough of the framework to support it.

Figurel is a front elevation of the machine with a portion of the framework broken away; Fig. 2, a vertical section on theline 2 2 of Fig. 1; Fig. 3, a detail perspective View of one of the pawl-supports and plate carried thereby; Fig. 4:, a detail rear elevation of the same, and Fig. 5 a detail plan view of one of the segments and co-operating parts.

The same letters of reference are used to indicate identical parts in all the figures.

The indicators consist of cylinders A or segments thereof carried by'vertical spindles B. Fast upon the lower end of each spindle is a gear 0, which meshes with a rack D upon the side of an oscillating segment E, loosely mounted upon a shaft F. When the segment is oscillated back and forth, the indicator will be turned to different positions to expose different numbers at theusual reading-opening or window in the casing, the particular number exposed being determined by the extent of movement given the segment E.

The segments E are oscillated back and forth and the extent of their movements determined by the following means and in the following manner: The shaft F is a rock-shaft and is oscillated back and forth a given distance at each operation of the machine by a crank-and-pitman connection with a revolu- The shaft F has an arm H, fast upon its left-hand end, and this arm is connected by a link I to an arm or crank J, fast upon the end of the shaft G. The latter has upon its right-hand end an operating-handle K, by which it may be given a complete revolution at each operation of the machine. Fast upon the shaft F, beside each segment E, is an arm or pawl-support L. Pivoted to the rear side of this support at M is a plate N, having its upper end shaped to extend forward over the support L. Projecting from its upper left-hand corner is a lug or tooth O, which co-operates as a pawl with teeth P, formed upon the right-hand side of the segment. The plate N is free to be rocked upon its pivot M to engage the teeth 0 with and disengage it from the segment E. The upper end of the support L is formed into a tubular housing, which contains a coiled spring Q, (dotted lines, Fig. 2,) and a plug R, having a a pointed upper end engaging the under side of the forwardly-extended portion of the plate N. This plug serves to yieldingly hold the plate N in its different adjusted positions. Upon the upper face of the plate N is formed a beveled lug S, which co-operates with the series of keys T, whose stems stand substantially in line with it. WVhen the keys are in their normal position, their inner ends do not project into the path of travel of the lug S; but when any one of them is pushed inward its inner end may be brought into the path of the lug.

When the machine is at restand the parts in normal position, the supports L stand in substantially-vertical position, Fig. 2, and a beveled lug U upon the under side of the cross-bar V of the framework has moved the plate N to the right, Fig. l, and carried its lug S to the right of the line of the row of keys T. If any keyin the row be now pushed in and the handle K given a complete revolution, the lug S will clear the operated key as it is carried forward and downward by the oscillation of the shaft F. Just before it reaches the end of its forward movement, however, the lower right-hand corner of the top of the plate N will strike a beveled lug W upon the lowercross-barX of the framework, and the plate will be thrown to the left, bringingthe lugSinto linewith therow of keys. The inner end of the operated key" will now stand directly in the path of the return travel of the lug S, and when the lug reaches the key its beveled right side will engage it and the plate N be thereby thrown to the left and its tooth 0 be engaged with one of the notches between the teeth P on the segment, thereby locking the segment to the oscillatory shaft F. From this point on in the return movement of the parts the segment will be carried with the shaft and the indicator A be turned accordingly. As the parts reach normal position the lug S will engage a beveled lug U upon the cross-bar Vand the plate N be thrown to the right again into the position shown in Fig. 1, and its tooth 0 be thereby disengaged from the segment E. At the next operation of the machine and forward movement of the shaft F a lug Y, projecting from the left-hand side of the arm or support L, will engage a lug Z, projecting into its path from the right-hand side of the segment E, and thus pick up the segment and carry it forward with it to the position shown in the drawings, thus restoring the indicator A to zero. If no key in the row co-operating with this segment has been pressed in at this second operation of the machine, the segment will be left in the position shown, when the shaft F and parts carried by it return to nor- 436,246, filed June 10, 1892, I have shown and described, but not claimed, some of the novel features of construction which form the subject-matter of this specification.

mal position, and the indicator geared to the segment will remain at zero.

Formed upon the upper face of the plate N, to the right and in front of the lug S, Figs. 3 and 5, is a cam A. In the backward movement of the shaft F and parts carried by it this cam follows immediately after the lug S and serves to throw the operated key outward to normal position after the lug S has passed it and the plate N been thrown to the left and its tooth O engaged with the segment. It will be understood that the adjustment of the parts is such that each operated key will throw the plate N into engagement with the segment E at just the proper point to cause the further return movement of the shaft F to carry the segment far enough to turn the indicator A to position to expose to view the number corresponding to such key. Thus the 9 key will throw the plate N to the left and engage its tooth O with the segment at almost the beginning of the backward movement of the shaft, and thereby carry the segment far enough to turn the indicator to the number 9,while the 2 key will not throw the plate N into engagement with the segment until the shaft has nearly completed its backward stroke, and will consequently carry the segment only far enough to turn the indicator to the number 2.

Heretofore in machines employing segments of this character coupled to and uncoupled from a driving mechanism at different points determined by the operated keys the indicators geared to the segments have been mounted to oscillate upon a horizontal axis parallel to that of the segments, and so far as I am aware I am the first in the art to mount the indicators upon vertical spindles geared to such segments. Such being the case my invention is not restricted to details of construction or arrangement of the parts, nor to the character of the connecting devices between the driving shaft and segments.

Those which I have shown and described are not new, and any other known or suitable devices may be employed, operating either to connect the driving mechanism with the segments at different points and disconnect them at a fixed point, as described in this specification, or to connect them at a fixed point and disconnect them at different points, as may be done in a number of well-known ways.

Owing to the fact that in the machine illustrated in the drawings of this application the indicator-spindles are not located in the vertical plane of the axis of the segments, they are geared together by a skew-gear and rack; but if the spindles were located directly over the'axis of the segments they could be geared together by an ordinary beveled gear and rack. Again, while I have shown the indicatorspindles geared directly to the segments as the simplest arrangement of them, yet if it i be desired to change their relative positions they may be indirectly geared to each other. In another pending application, Serial No.

Having thus fully described my invention, I claim 1. In a cash-indicator, the combination of an oscillatory segment geared to an indicator oscillating on an axis at an angle to the axis of said segment, and a driver intermittently connected to said segment, substantially as described.

2. In a cash-indicator, the combination of the oscillatory segment E, geared to the indicator A, oscillating on an axis at an angle to the axis of said segment, a driver, and means for intermittently connecting said driver and segment, substantially as described.

3. In a cash-indicator, the combination of a segment oscillating on a horizontal axis, a

driving mechanism, means for connecting the segment with and disconnecting it from the I driving mechanism, and an indicator oscillat-' ing on a vertical axis and geared to the segment, substantially as described.

mounted thereon, means for connecting the shaft with and disconnecting it from the segments, and the vertical spindles B, geared to the segments and carrying the indicators A,

substantially as described.

5. In a cash-indicator, the combination of the revoluble shaft G, the rock-shaft F, the crank-and-pitman' connection between them, the oscillatory segments E, loose on the shaft F, the plates N, pivoted 011 the supports L, fast on said shaft, means for shifting the positions of the plates N to connect and disconnect the shaft and segments,- and the vertical spindles B, geared to the segments and carrying the indicators A, substantially as described.

6. In a cash-indicator, the combination of the rock-shaft F, the oscillatory segments E,

segments at an angle to the shaft F and carrying the indicators A, the arms or supports L, fast on the shaft F, the plates N, pivoted upon the supports L and each provided with the tooth 0, lug S, and cam A, and the keys T and cams U W, co-operating with the plate N, substantially as described.
